Cursoring with arrows from outside a table into it and typing causes pawns.

To reproduce:

1. Open standalone 'empty.html' demo.
2. Insert → Table.
3. Click to place cursor in empty paragraph after the table.
4. Press 'Left arrow' once.
   • You get a linear selection inside the last table cell (according to debug bar), but no cursor is visible.
5. Try typing.
   • Nothing happens. It is, however, possible to paste some text into the cell with the invisible cursor (Ctrl+V).
